It was a packed courtroom today as Harlow Cuadra and his former lover Joseph Kerekes finally took the stand in the capital murder trial of Cuadra.

Investigators allege the pair killed gay porn producer Bryan Kocis, 44, in his Dallas Township, Pennsylvania home in an effort to cut free Kocis' biggest star, Sean Lockhart, from his contractual obligations. The two men operated a rival online gay porn business and believed a film staring Lockhart and Cuadra could be worth $1 million.

Kocis' body was found by firemen responding to a fire at Kocis' house on the night of January 24, a Wednesday, his neck slashed to the point of near decapitation and his torso stabbed 28 times.

Kerekes, 35, pleaded guilty to second-degree murder last December and is now serving a life sentence without parole. He previously pledged he would not testify against his former lover, and jurors heard from him today.

“I've been thinking a lot about my parents,” Kerekes told the jury. “It would destroy them to say I did something I didn't do.”

In his testimony, Cuadra, 27, who spent hours on the stand, blamed Kerekes for the murder, reports WNEP an ABC affiliate.

“Takes out this knife and slashes him. Bryan immediately grabs his throat,” Cuadra told the court.

Teary-eyed Cuadra told jurors he was not a killer, and that he had been sexually molested at the age of 8.

Harlow Cuadra could face the death penalty if found guilty of the murder of Bryan Kocis.
